Abstract: A method for changing only one radio channel of an existing duplex radio link is wherein the radio channel changed or to be changed is the disturbed radio channel. The new radio channel (Dn) exhibits, for example in comparison with the disturbed radio channel, only a different timeslot wherein, the radio frequency remains the same.

Abstract: A transmission facility (UE) for the transmission of information via power supply lines (EV) is integrated into the charging device (L) for mobile communication devices (M). Personal computers (PC) connected to these power supply lines (EV) can gain access to other networks such as local or broadband networks (LAN, WAN) via the inserted mobile communication device (M). The integration means that essential components of the charging device (L) have multiple applications and access overall is realized cost effectively.

Abstract: Method for avoiding communication collisions between co-existing PLC systems on using a physical transmission medium common to all PLC systems and arrangement for carrying out said method

Abstract: The invention relates to a method for rapidly synchronizing communication stations belonging to mutually independent PLC networks without reducing the user data rate. According to said method, the respective communication stations transmit or receive basic information at respectively the same time with regard to a cycle of the network frequency of each PLC network that is assigned to the respective communication station. The information is respectively transmitted with the same regularity with regard to a cycle sequence of the network frequency of each PLC network that is assigned to the respective communication station.
